I'm having a weird issue. I was messing around with my stylesheet on my blog, and when I went to the Sidebar Arrangement page, I had 7 EXTRA sidebars to add widgets to. There's so many, they stretch off the right side of the screen. They also have "admin1", "admin2", etc. over them.
The only file I've been editing is my stylesheet file for the theme of my blog; nothing else.
